The round robin clock, RTC_CLK,&nbsp;high frequency limit mainly depends on facts:DAC&nbsp;initialization time. fRCLK &lt; 63 / Tinitialization (it's 30us in S32K344). so&nbsp;RCLK should be smaller than 2.1MHz.</P><P>But, RCLK has four clock resource: SXOSC(32.768kHz). SIRC(32kHz), FIRC(the smallest value is 3MHz),FXOSC(the smallest value is 8MHz).</P><P>So, How could i get 2MHz?</P><P>i want to use cmp to detect the over current of 6 channels. but the RCLK is too long as i understand.&nbsp;Do I have to use an external comparator?&nbsp;</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Neo1096_0-1713165039619.png" style="width: 400px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/273678iCFBDE94995CF4432/image-size/medium?v=v2&amp;px=400" role="button" title="Neo1096_0-1713165039619.png" alt="Neo1096_0-1713165039619.png" /></span></P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Neo1096_2-1713165315677.png" style="width: 400px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/273680i550C4E30D3FD610D/image-size/medium?v=v2&amp;px=400" role="button" title="Neo1096_2-1713165315677.png" alt="Neo1096_2-1713165315677.png" /></span></P><P>&nbsp;</P> Mon, 15 Apr 2024 07:15:25 GMT https://community.nxp.com/t5/S32K/S32K344-LPCMP/m-p/1846846#M34192 Neo1096 2024-04-15T07:15:25Z https://community.nxp.com/t5/S32K/S32K344-LPCMP/m-p/1851674#M34503 <P>Hi <a href="https://community.nxp.com/t5/user/viewprofilepage/user-id/229677">@Neo1096</a>,</P> <P>This is specified in the RM.</P> <P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="danielmartynek_0-1713792811153.png" style="width: 611px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/275041i600BA1753B70F926/image-dimensions/611x331?v=v2" width="611" height="331" role="button" title="danielmartynek_0-1713792811153.png" alt="danielmartynek_0-1713792811153.png" /></span></P> <P>&nbsp;</P> <P>I don't know the use case so I can't help with that.</P> <P>&nbsp;</P> <P>Regards,</P> <P>Daniel</P> Mon, 22 Apr 2024 13:35:57 GMT https://community.nxp.com/t5/S32K/S32K344-LPCMP/m-p/1851674#M34503 danielmartynek 2024-04-22T13:35:57Z
